Sulfurization of meteoritic metal in H2S-H2 gas produced three different sulfides: monosulfide solid solution [(Fe, Ni)(1-x)S], pentlandite [(Fe,Ni)(9-x)S8], and a phosphorus-rich sulfide. The corn position of the remnant metal was unchanged. These results are contrary to theoretical predictions that sulfide formation in the solar nebula produced troilite (FeS) and enriched the remaining metal in nickel. The experimental sulfides are chemically and morphologically similar to sulfide grains in the matrix of the Alais (class Cl) carbonaceous chondrite, suggesting that these meteoritic sulfides may be condensates from the solar nebula.
